The data shown in the table below were obtained from a tensile test of high-strength steel. The test specimen had a diameter of 13mm and a gage length of 50mm. At fracture, the elongation between the gage marks was 3.0mm and the minimum diameter was 10.7mm. Plot the conventional stress-strain curve for the steel and determine the propotional limit, modulus of elasticity (i.e the slope of the initial part of the stress-strain curve), yield stress at 0.1% offset, ultimate stress, percent elongation in 50mm, and percent reduction area.

An engineer determines that a 32 cm long rod of 1020 grade steel will be subjected to a tension of 40 kN. The following two design requirements must be met: the stress must remain below 120 MPa, and the rod must stretch less than 0.135 mm. Determine an appropriate value for the rod's diameter to meet these two requirements. (Round up to the nearest millimeter when reporting your answer.) mm
